Abstract: With the thermo-electric conversion element according to the present invention, the power generating efficiency (in other words, the conversion efficiency) can be improved by inserting as metallic film made of either Ag, Al, or silver soldering material for the PN junction formation between the Si based P type and N type semiconductors and inserting a metallic film made of either Zn, Ni, Cu, Ag, Au, or Cu-30Zn at a connecting portion between the semiconductors and lead wires, so that the electromotive power and the thermo-electromotive force are not cancelled each other due to the Schottky barrier which is generated at the interfacial area between the metals and semiconductors. The desired thermo-electric conversion efficiency can be achieved by the material presented in this invention without any deterioration of the original thermo-electric properties.

Abstract: The invention relates to a process for the transmission of signaling and control information for wavelength-division multiplex networks (1) for optical, fibe r- bound information transfer in digitized form, the signaling and control informatio n being transmitted via the same optical channel, particularly with the same wavelength, as the user information, but being coded and decoded independently thereof, with th e result that the control and signaling information can also be accessed independentl y of the user information. The use of a time-division multiplex process allowing the different coding of user information and control information makes it possible considerably to reduce the technical complexity of passive optical network elements with regard to the routing of the signaling and control information. The process according to t he invention permits the simple, low-cost and transparent transmission of signaling and control information in optical WDM networks.

Abstract: A method and apparatus to segment-wise detect and bring into coincidence signal waveforms which can be converted into monotone and continuous trajectories, in particular for purposes of real-time pattern recognition, localization and monitoring optical and acoustic signals and to determine transit-time differentials.      The desired monotone and continuous trajectories are made to coincide in translation-invariant manner with the key signal waveforms which are also storable in reconfigurable manner. The said method and apparatus therefore detects in a very short time said trajectories with high accuracy of measurement. Even in other applications (Fig. 3), the determination of transit-time differentials implemented by the method of the invention takes the form of detecting key signal waveforms in the upper or lower signal detection unit C1a or C1b and in further processing the data in the subsequent multi-coincidence unit C2, shift-invariant parallel multi-template matching being carried out in the detection units C1a and C1b, wherein the trajectories are correlated in parallel and a set of transit-time differentials in the form of an output vector D being emitted from the subsequent multi-coincidence unit C2. The method is suitable to accurately determine trajectories and accordingly is useful for instance to localize signal sources in space, to measure displacement trajectories, to measure speed and acceleration, etc.

Abstract: A wireless communications system and method controls network load by selectively scaling aggregate base station transmit signals. In one implementation, aggregate in-phase (I) and quadrature (Q) channel transmit signals are multiplied by a scaling coefficient output by an aggregate overload controller based on load levels relative to a threshold.      By scaling aggregate I- and Q-channel transmit signals when load level measurements indicate a high load situation, handoff control measurements made at mobile subscriber terminals, such as received signal strength from the base station, bit/frame error rates, and signal-to-noise ratio, will be affected, thereby prompting mobile subscriber terminals at the cell/sector boundaries to request handoff to an adjacent cell/sector. Thus, load is balanced between a number of cells/sector to increase network capacity and prevent overload without relying on a call admission/blocking scheme.

Abstract: A carbon composite structure, for example, an automotive engine piston, is made by preparing a matrix comprised essentially of a mixture of non crystalline particulate soluble in an organic solvent and a binder that has a liquid phase. The non crystalline particulate also contains residual carbon hydrogen bonding. An uncured structured is formed by combining the matrix mixture, for example, carbon fibers such as graphite dispersed in the mixture and/or graphite cloth imbedded in the mixture. The uncured structure is cured by pyrolyzing it in an inert atmosphere such as argon. Advantagesoulsy, the graphite reinforcement material is whiskered prior to combining it with the matrix mixture by a method involving passing a gaseous metal suboxide over the graphite surface.
